说明：  对通用的编解码算法进行了分析和比较。、对有限域基本算法,包括加法、乘法以及求逆的实现进行了研究,并在matlab中进行了软件编程,最终综合了性能及速度等因素,使用了比较简单、易于实现的逻辑运算作为硬件实现的基础。
(For general decoding algorithm are analyzed and compared. , the basic algorithm of finite field, including the addition, multiplication, and the realization of inverse are studied, and the software programming in matlab, finally comprehensive performance and speed and other factors, using the logic operation is simple, easy to implement as the basis of hardware implementation. )
